I put a set of 27" 589s with aluminum rims on my Rincon. They are very heavy and offset pretty far (bigfoot kit). You could def tell they were on there.....Rincon lacked power. I was thinking of putting just the tires on the stock rims, but wondered where most of the weight of the Bigfoot kit comes from....? Are the 589 tires that much heavier than stock OR are the aluminum rims that much heavier than stock steel ones? I was also considering the stock wheels because the Bigfoot kit was offset too far in my opinion. Thanks.
